The donor recovered this navigation lamp before the 1980s from an old storage area in a South Melbourne factory where he worked. He asked about the lamp, but nobody there knew anything about its origin, and he was told that he could have it. This is a complete ship navigation lamp with its original oil burner. The internal red colour and shape indicate that the lamp was used for the port side of a vessel. The burner assembly is fixed to a removable tray, and the burner disconnects from the tank to allow fuel to be added. Light showing from the lamp is magnified by the polished brass reflector behind it, and the painted internal surfaces give the light its red colour. The lid on the chimney unclips for inspection purposes. The wedge shape of the lamp is intentional. It allows the light to be visible horizontally from up to a 112.5-degree angle, and to be invisible past that angle. The light's colour and position are part of the code of signals that inform viewers of the vessel’s position, direction of travel and status. The red lights indicate the port side of a vessel, green lights indicate the starboard side, and white lights are used on the masthead. From 1972, lights and signals on marine vessels are required to be fitted according to the International Regulations for Preventing Collisions at Sea. SEAHORSE lamp, made in Britain: The firm Bocock & Wilkinson was established in Birmingham in 1890 as an electroplate manufacturer. In 1900, Kelly’s Directory lists the firm as a ship lamp manufacturer. In 1910, the firm was listed Trading As “Seahorse” at 17 & 18 Mott Street, Birmingham. The firm later became Bocock & Son, and in 1932 was listed as George Bocock & Co. Ltd, and in 1973, it was still at that address.
